In this way, the materials are conveniently grounded, and the supporting framework 18 is also conveniently clamped by utilizing the conductive protrusion 185 in the injection molding process of the case body, so that the uniformity of the protective coating 19 is sequentially improved.

[0139] In some embodiments, a plurality of conductive protrusions 185 are provided, and the plurality of conductive protrusions 185 are disposed on the supporting framework 18 at intervals. A plurality of second avoidance openings are provided, and the plurality of second avoidance openings and the plurality of conductive protrusions 185 are disposed in one-to-one correspondingly manner.

[0140] The conductive protrusion 185 includes a first end surface and a second end surface which are oppositely disposed, the first end surface being connected to the supporting framework 18, and the second end surface of the conductive protrusion 185 and a surface of the protective coating 19 being located in the same plane. Through the arrangement, an inner wall surface of the containing space 100 can be flat and the problem that the conductive protrusion 185 protruding the protective coating 19 may scratch a transport bag is avoided.

[0141] In some embodiments, a bottom surface of the case body 1 is provided with a grounding column 186, and the grounding column 186 is connected with the supporting framework 18, so that the materials are grounded through the grounding column 186.

Through the arrangement, the first locking part 291 and the second locking part 292 are hooked to each other, so that the first locking part 291 and the second locking part 292 are blocked from each other to prevent the first door body 27 and the second door body 28 moving towards the opening direction, and improve the locking strength of the first door body 27 and the second door body 28. When the case body 1 needs to be opened, only the first locking part 291 or the second locking part 292 needs to be rotated for separation, thereby opening the case body 1.

When the auxiliary door 6 is opened, the rotating component 70 is disposed in the connecting channel 710 in a penetrating manner, so that the separation of the auxiliary door 6 and the second side plate 52 is avoided through the blocking effect of the rotating component 70 and the connecting channel 710. In the use process, the operator only needs to pull the auxiliary door 6 with force, so that the first fixing part 57 is separated from the second fixing part 60, that is, the auxiliary door 6 is opened.

[0194] In some embodiments, the second side plate 52 with a first end surface 5011, a second end surface 5012 and a third end surface 5013 which are connected with each other, and the first end surface 5011 is opposite to the third end surface 5013 to enclose the auxiliary opening 507 between the first end surface 5011, the second end surface 5012 and the third end surface 5013.

The auxiliary door 6 is driven to rotate through the stopping effect between the connecting shaft 702 and the second connecting plate 712 and the third connecting plate 713, so that when the auxiliary door 6 is in the open position, the connecting shaft 702 applies an acting force to the first connecting plate 711 to prevent the auxiliary door 6 from falling.
